Dear all,

I installed opnsense firewall quite sometimes ago n this recently happen to my opnsense box.
I unable to ping from LAN to opnsense or opnsense to LAN. I don't know why, i did not alter any firewall rules.
I cannot even browse the OPNSense GUI from LAN nor connect to internet.
Is this sign of hack because last week i did encounter this issue and i did reinstall everything but now i want to recover via cli.

How to recover it? Thanks in advance.

Can someone help to highlight this issue to FreeBSD Developers?

Did you take a look at this topic?

https://forum.opnsense.org/index.php?topic=9741.0

I tried read the posts but still not understand it.

1. Configure the WAN interface as none (IPv4 Configuration Type none)
2. Add a new OPT interface with the PPPoE configuration just like it was a WAN PPPoE.
3. Configure Suricata as IPS on WAN.

Suricata IPS mode on PPPOE is not permitted.

Dear all forumers, I want to install wazuh manager(Not Agent) within opnsense box. What is the package for it? What command?

Need to use VPN then it can stream youtube.

Other sites working perfectly, just youtube didn't working. I don't have squid.

Dear all, I open browser to watch youtube but unfortunately I cannot stremam any videos or login. Any things wrong?

Dear all, I'm using PPPOE connection and how to activate Suricata IPS mode?

I using command to install pkg install os-crowdsec.

I not able to start crowdsec services. When to check the log files?
I go System-Diagnotics-Services.

Dear all,
I did a fresh installation of my opnsense but found out that crowdsec was not offer as plugins. How to install crowdsec?

Dear forumers, I had configured several cron jobs in opnsense web gui. My cron job is to reset the wan ip address every 15 minutes.

*/15    *    *    *    *    Reset WAN Interface    Periodic interface reset   


I tried to monitor the firewall logs and its block logs doesn't reflect the changes of wan ip address every 15 minutes. It doesn't change the wan ip address. Besides this, all my cron job doesn't take effect.

Please point me in the right direction to figure out what wrong with it.

I didn't configure anything for crowdsec except the collections.

Then you should probably follow the documentation I linked.

OK then, let me try to do it. Thanks.

Did you configure your private networks for crowdsec? I.e. is the default whitelist parser installed or did you create one manually a documented?

https://docs.crowdsec.net/u/getting_started/post_installation/whitelists/

I didn't configure anything for crowdsec except the collections.

Root cause:

1. OSCrowdsec service stop for temp
2. OPT1 no IP address (No lights) Swith to LAN port for now.

Questions:
1. Why crowdsec blocking my LAN - It detect connection IN?
